impact of self-care education on self-efficacy and quality of life of late adolescents with congenital heart disease

Background: self-care of adolescents with congenital heart disease (chd) is one of the challenges of the health care system. chd is a common chronic disease that affects the quality of life (qol) and self-efficacy of adolescents. this study compares the effectiveness of self-care education by face-to-face method and video clip (vc) on self-efficacy and qol in late adolescents with chd.methods: this research was a non-randomized clinical trial. a total of 111 late adolescents aged 18 to 21 years with chd referred to rajaie cardiovascular, medical, and research center in tehran, iran, were recruited by convenience sampling and non-randomly assigned to either control, face-to-face (f2f), or vc groups (37 subjects in each group). the f2f group participated in two educational sessions (each lasted 35-45 minutes) with an interval of one week, and the vc group received a 90-minute video to watch at home. the study data were collected before (t1) and two months after the intervention (t2), using the generalized self-efficacy (gse) scale and world health organization’s quality of life questionnaire (whoqol-bref) and analyzed in spss version 19 software using the chi-square test, fisher test, paired t test, scheffé test, and anova. the significance level was set at p<0.05.results: before the intervention, demographic variables, self-efficacy, and qol were not significantly different in the three groups. the self-efficacy significantly increased in the f2f (p<0.004) and vc groups (p<0.031) at t2. furthermore, qol dimensions significantly improved in the f2f and vc groups (p<0.05), except for the environment dimension (p>0.05).conclusion: self-care education through f2f and vc significantly affects the self-efficacy and qol of late adolescents. such educational programs can greatly reduce the possible complications of the disease by empowering this group.
